I T all 'wltom z'tmayconcern:

Be it known that I, SoLoMoN STEIN, a citizen of the United States, residing at Washington, in the District of Columbia,-

provide improved means for setting a. stone 7 in a mounting in such manner that it is held firmly and. rigidly in position and permits thesetting of stones of different sizes in the same mounting as occasion may .re

' quire.

A further object of. the, invention is to provide a mounting having upon the inside a screw-threaded opening with an overhang or shoulderat the upper and outer end 7 with a screw-threaded sleeve of improved type insertible into thescrew-threaded opening against thefstone held by the over-hang and retaining such stone firmly inposition.

A further object of the invention is to provide .means for setting a stone in a "mounting of any'usual and ordinarytype in such manner that as occasion may require the stone may be removed from the mounting and replaced by a, diflerent stone but to beretained firmly and securely in position-until .so manually removed.

A further object of the invention is to provide a mounting fora stone which is furnished in predetermined sizes so that the same equipment both as to the mounting and the" means for retaining the stone may be employed for stones difiering and varying in size. v "With these and other objects in view the invention comprises certain novel parts, units, elements, constructions, combinations, arrangements and. functions, asdisclosed in the drawing, together with mechanical equivalents thereof, as will be hereinafter more fully described and claimed.

In the drawings:

' Figure 10 is the internally screw threaded sleeveused for-the square'settin r as at F igure 11 into which the threaded at Figure 9 is inserted; V

,Figure 1-1 is a fragmentarydetail sectional view of theunder side of amounting with "a square opening; with I the two sleeves in position to hold a stone; and

- Figure 12 is-aview in side elevation of the sleeve-to be inserted into-"the threaded opening. of .the mounting shown at Figure 3.

Like characters of reference indicate-corresponding parts throughout the'several views. It is well known that in-the' usual-setting of stones in articles of jewelry, as-for instance in a ring, an opening is provided for inset as claws engaging the edge 0 the stone for holding the stonejinpositions i The setting of a stone in this manner'is a-'delicate operation, as the" claws mustbe forced inwardlyexactly 'the right distance to properly clamp the stone, which results many times in breaking the stone/while setting. In the present case the mounting is provided with an opening from "the'u'nder or reverseside into and throughwhichthe stone is inserted. At Figure 1 the stone 10 sleeve shown 4 are 7 is of substantially the same size as the screwthreaded opening 11 in the ring 12 for mounting a gem or the like. At the top, however, an overhang or shoulder 13 is provided against which the inclined sides or facets of the stone engage at the edge. A screw-threaded sleeve, shown as an entirety at let, is inserted into the threaded opening 11 engaging the under side of the stone, clamping it firmly against the overhang 13. The threaded sleeve 14: is preferably provided with sometorm of opening or recess, as the notch 15, for engaging a wrench or tool or spanner of some nature for tightening the sleeve in position, and when in position a portion of the sleeve is swaged into a recess 16 in the mounting, preventing its return movement except when force is applied thereto for the purpose oi withdrawing the sleeve. WVhen set in a ring the sleeve would be provided with a concave formation at the bottom, as indicated at 17, to conform to the curvature of the rin Vhen, however, the stone and sleeve are set in a different form of ornamental ware, as the brooch 5 or the braclet 6, the bottom may be perpendicular to its axis, as indicated at 18. The brooch or bracelet is provided with a similar overhang 19 engaging the stone 10 in the same manner It is the intent of the present invention to furnish the screw-threaded sleeve 14 in indeterminate length, as shown in Figure 9, in which case it is desirable to drill or perforate the screw at intervals, as indicated at 20, so that when out to the required length an instrument or point may. be inserted in any 01: these perforations for the purpose of rotating the sleeve to clamp the stone in position.

At Figure 3 is shown the form of mounting furnished ordinarily by the manufacturer to the jeweler, the top 21 being ordinarily perforated only with a small opening as shown at 22 which is reamed out by the jeweler to fit any size of stone required.

.r-is shown in dotted lines two sizes are suggested, it being obvious that variation of size is only limited by the size of the mounting; that is to say in case the stone to be set in the mounting is not oi such size as to completely fill the maximum opening 11, the opening as indicated at 22 is reamed out and tapered only sutlioiently large to engage the edges of the stone in the manner hereinbefore mentioned, and a sleeve as shown at Figure 8, thicker at the stone-engaging end than the sleeve indicated at Figures 2 and 12, will be employed so that itwill engage the under I side of the stone and clamp it firmly in position in the same manner.

A certain type of mounting is now furnished to jewelers having what is known as a square opening, indicated at 24. This opening has its corners removed so that it is not internal screw threads in this sleeve fitting the external screw threads of the clamping sleeves furnished so that this clamping sleeve 26, as shown at Figure 11, will be identical with the other clamping sleeves, but instead of engaging directly the mounting as turnished, they will engage the intermediate sleeve 25, as shown at Figure 11.

At said Figure 11 a square in double dotted lines is shown. The inner dotted squareis intended to represent the opening in the front of the mounting, while the outer square represents a square stone with its margins engaging the margins of the openin It will be obvious that the stone will be placed in such position with the sleeve 26 removed, which sleeve will thereafter be Placed in position within the sleeve 25 clamping the stone in position.

At Figure 2 the mounting 12 is shown as provided with side openings 27, such openings, however, being purely ornamental, but in that case the sleeve let after setting is drilled with registering openings 28, simply to carry out the ornamental effect of the complete setting.

in any event, the back of the stone is at all times visible through the sleeves 14, 18

or 23 to get any effect oflight which may be desired thereby, or for the purpose of examining the back of a stone when inspection is desired. It will be apparent that the mountings of various types, rings, or other articles of jewelry, may be and will be furnished the jewels unset, but with the openings in the back properly drilled and threaded to receive the threaded sleeve shown in indeterminate lengths, as shown at Figure 9. The mounting will be properly prepared to receive the stone, as by reaming out the opening 22 shown in the ring at Figure 3 until the stone extends the desired distance abovethe top of the mounting with onlythe edge of the stone engaged by the overhang and the sleeve is then cut to the proper length and seated after which it is upset as indicated at Figure l merely for the purpose of preventing accidental displacement. In this manner stones of various sizes may be quickly and readily set in stone mountings without dan of stone after setting.
